Ikelite FL Modular Port Extension for Lenses up to 3.5"

This Extension screws onto Ikelite's FL Modular 8" Dome Port or FL Modular Flat Port, each of which accommodates lenses attached to DSLRs or mirrorless cameras in Ikelite underwater housings. When used with the dome, this extension is compatible with many short zoom lenses measuring up to 3.5" long and 3.3" in diameter. When used with the flat port, it accommodates lenses up to 3.4" long. Compatible models include those from Canon, Nikon, Sigma, Tamron, Panasonic, Olympus, and Sony. For a list of lenses that can be used with the extension, please see the following port charts: FL, FL for Panasonic Lumix GH3/GH4 Housings, and FL for Sony Alpha 7-series Housings. This extension has the same standard 200' depth rating as most Ikelite ports and housings.
